A series of novel 1,3,4-oxadiazole derivatives based on structural and electronic overlap with combretastatins have been designed and synthesized. Initially, we tested all new compounds in vivo using the phenotypic sea urchin embryo assay to yield a number of agents with anti-proliferative, anti-mitotic, and microtubule destabilizing activities. The experimental data led to identification of 1,3,4-oxadiazole derivatives with isothiazole (5-8) and phenyl (9-12) pharmacophores featuring activity profiles comparable to that of combretastatins, podophyllotoxin and nocodazole. Cytotoxic effects of the two lead molecules, namely 6 and 12, were further confirmed and evaluated by conventional assays with the A549 human cancer cell line including cell proliferation, cell cycle arrest at the G2/M phase, cellular microtubule distribution, and finally in vitro microtubule assembly with purified tubulin. The modeling results using 3D similarity (ROCS) and docking (FRED) correlated well with the observed activity of the molecules. Docking data suggested that the most potent molecules are likely to target the colchicine binding site. (C) 2010 Elsevier Masson SAS. All rights reserved.

In a document, author is ELAZHARY, AA, introduce the new discover, Quality Control of (2-Nitrovinyl)benzene.

Optimized geometries, harmonic force fields, and dipole derivative tensors were computed for isoxazole and isothiazole with HF, MP2, DFT, and MCSCF methods using the 6-31G** atomic orbital basis set. The ab initio force fields were scaled to form scaled quantum mechanical (SQM) force fields using the experimental fundamental frequencies for isoxazole-d(0) and -d(3) and isothiazole-d(0), -4-d(1), -5-d(1), and -4,5-d(2). The calculated frequencies confirmed the experimental assignment for isothiazole and its isotopomers and showed up possible misassignments for isoxazole and its -d(3) isotopomer. The computed atomic polar tensors were used to calculate the IR absorption intensities. The best agreement between the calculated optimized geometries and IR absorption intensities and the experimental results was obtained with density functional calculations, but the correlation between the scale factors determined for both molecules was worse than those calculated at the MP2 and HF levels. With MP2 the optimized geometries were slightly worse than those at the DFT level, the calculated IR absorption intensities were in excellent agreement with the experimental IR absorption intensities for the in-plane modes but in poor agreement for the out-of-plane modes, and the correlation between the scale factors determined for both molecules was excellent. The HF- and MCSCF-optimized geometries and IR absorption intensities are slightly worse than the density functional results. Although the geometry and the intensity for the in-plane modes are calculated correctly with MP2, the large disagreement of the out-of-plane modes indicates a strong static correlation. The correlation between the scale factors determined with HF was worse than that at the MP2 level but better than that of the density functional and MCSCF calculations.

With the volume and accessibility of scientific research increasing across the world, it has never been more important to continue building the reputation we’ve spent the past two centuries establishing. 2307-69-9, Name is Isopropyl 4-methylbenzenesulfonate, molecular formula is C10H14O3S, Application of 2307-69-9, belongs to isothiazole compound, is a common compound. In a patnet, author is Nakae, Koichi, once mentioned the new application about 2307-69-9.

Natural products have contributed to the elucidation of biological mechanisms as well as drug discovery research. Even now, the expectation for natural products is undiminished. We screened prostaglandin release inhibitors that had no effect on in vitro cyclooxygenase activity derived from natural product sources and discovered pronqodine A. Using spectral analysis and total synthesis, the structure of pronqodine A was shown to be a benzo[d]isothiazole-4,7-dione analogue. Evaluation of the biological activity of pronqodine A revealed that the NAD(P)H dehydrogenase quinone 1 (NQO1) converted pronqodine A into a two-electron reductive form. The reductive form underwent autoxidation and reversed to its native form immediately with the generation of reactive oxygen species. Further investigations proved that pronqodine A inhibited cyclooxygenase enzyme activity only in the presence of NQO1. Pronqodine A acts as a potential bioreductive compound, inhibiting prostaglandin release in selectively activated NQO1-expressing cells.

Isothiazole dioxides have been shown to inhibit Trypanosoma brucei protein. farnesyltransferase (PFTase) in isolated enzyme, but elicited only a minor effect on mammalian PFTase. In the present study we have evaluated the effect of 3-diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxides with different substituents at C5, on rat PFTase and protein geranylgeranyltransferase-I (PGGTase-1) with the final aims to improve the potency against mammalian PFTase and to identify new compounds with antiproliferative properties. For these purposes, in vitro and cell culture models have been utilized. The results showed that isothiazole dioxides with C4-C5 double bond and sulfaryl substituted at the C5 position but none of the dihydro-derivatives, were able to inhibit in vitro PFTase in a concentration dependent manner (IC50 ranging from 8.56 to 1015 mu M). Among those, compound 6n (C5; methyl-S) displayed 500-fold higher inhibitory potency on PFTase than PGGTase-1. Compound 6n was shown to affect rat smooth muscle cell (SMC) proliferation at concentrations similar (IC50 = 61.4 mu M) to those required to inhibit [H-3]-farnesol incorporation into cellular proteins (-44.1% at 100 mu M). Finally, compound 6n interferes with rat SMC proliferation by blocking the progression of G0/G1 phase without inducing apoptosis, as assessed by [H-3]-thymidine incorporation assay and flow cytometry analysis. Taken together, we described a new PFTase inhibitor containing the isothiazole dioxide moiety that affects mammalian protein farnesylation and SMC proliferation by inhibiting G0/ G1 phase of the cell cycle.

The gas-phase high-resolution infrared spectrum of isothiazole in the range 600-1500 cm(-1) has been recorded, and revised band centres obtained for a number of vibrations. An analysis of the nu(11)(A’) band at 818 cm(-1) and the nu(16)(A) band at 727cm(-1) has been performed, using the Watson Hamiltonian, A-reduction, IIIr representation. These were combined with previous microwave spectral data to provide combined analyses for rotational constants and quartic centrifugal distortion constants Delta(J), Delta(JK), Delta(K), delta(J) and delta(K). These extend the knowledge derived from previous microwave and IR spectral studies. The equilibrium structures and the derived harmonic frequencies were calculated by ab initio methods, using a variety of basis sets with MP2, MP4 and CCSD(T) methods, and a comparison of these with experimental data is discussed. At a pragmatic level, the closest correlation of the rotational constants with experiment is not obtained with the most sophisticated methodology. Similarly, the vibration frequencies and intensities also vary strongly with the procedure. In particular, we found that the cc-pVTZ + MP2 results probably provide the best numerical comparison with experimental IR data for this molecule.
